Installation Notes and Tips

Verify the vehicle’s front axle configuration and confirm bearing dimensions before installation. Because the ABS sensor is not included, reuse or replace the vehicle’s existing sensor arrangement as required by the application. Inspect the hub, knuckle, and mating surfaces for wear or damage, and follow factory torque procedures during assembly. Confirm fitment for the exact year, model, and front position before ordering 951-157.
